.40 is losing popularity in LE and IDK how popular it ever was for non-LE, but when the used .40's are $100 less next to used 9's, the average person who is buying their first gun is looking to spend as little as possible knowing they are going to shoot it little. Those .40s will sell along with a few boxes of ammo and the buyer will be happy they walk away paying less than they did for a 9mm and ammo because they're not gun people and don't know any better.
You're 110% wrong about this. Nearly all 40 buyers these days are not new gun owners. I sold quite a few .40s.... Nearly ALL of them were bought by collectors, frequent fliers and 40 acolyte types. New shooters have ZERO interest in 40 at all unless they have a shitty retard friend standing behind them at the counter who's trying to push it on them.
Also basically if you go in any gun store of consequence there's only going to be one manufacturer's 40s on the shelf and that's going to be Glock. Others still make them but nobody bothers buying them. In some cases they might even be difficult to get from distribution for like Sig or S&W or somebody like that. Because nobody is buying new .40s unless it says Glock on the side of it. Ironically this results in a lot of retention of 40s unless a PD dumps them or somebody dies. Otherwise people don't bother trading them in although part of that is because there's that little nagging negative value problem. (Even Glock 40s suck on the flip, others are worse unless you're getting them on the cheap like in an estate situation).
This begs the question of what is it you are wanting from .357 Sig? You want it for a carry piece to run to the cigar store?
I don't want anything from it it's just something different. For the same reason a dog can lick its balls. I never was trying to advocate that it was actually a practical choice. For exactly the same reason that you advocate for stupid f***ing derringers, 32NAA and other guns that make no sense except I'd say a 357 Sig is a lot less dumb than that bullshit is.
A 9mm can do that just fine. You want it to go hiking in NH moose fukk and cum territory? 10mm or .45 is gonna be better for that.
There's almost no situation where .357 Sig becomes such a good choice it becomes worth paying triple what 9mm does and in the rare instances where .357 Sig actually is a superior choice to 9mm due to the extra power, that extra power pales in comparison to a larger caliber in a situation where carrying a larger gun is not an issue.
Blah blah blah. Still doesn't change the 357 Sig was a cool caliber that's about to go extinct.
